An antenna includes a substrate, and an array of dipole antenna elements on the substrate. Each dipole antenna element includes a medial feed portion and a pair of legs extending outwardly therefrom. Adjacent legs of adjacent dipole antenna elements include respective spaced apart end portions with impedance coupling therebetween. An impedance matching layer is adjacent a side of the array of dipole antenna elements opposite the substrate. The impedance matching layer includes an array of spaced apart conductive elements.

Phased array antenna with an impedance matching layer and associated methods

A phased array antenna ( ) includes a current sheet array ( ) on a substrate ( ), at least one dielectric layer ( ) between the current sheet array and a ground plane ( ), and at least one conductive plane ( ) adjacent to the substrate for providing additional coupling between adjacent dipole antenna elements of the current sheet array.

Multi-layer capacitive coupling in phased array antennas

An antenna includes a substrate including a ground plane and a dielectric layer adjacent thereto and at least one antenna unit carried by the substrate. The at least one antenna unit may include a plurality of adjacent antenna elements arranged in spaced apart relation from one another about a central feed position on the dielectric layer opposite the ground plane. The at least one antenna unit may also include an antenna feed structure including a respective coaxial feed line for each antenna element and a feed line organizer body having passageways therein for receiving respective coaxial feed lines.

Patch dipole array antenna including a feed line organizer body and related methods

A phased array antenna includes an antenna housing having a subarray assembly that supports beam forming network modules and an array face defining a ground plane substantially orthogonal to the subarray assembly. A plurality of millimeter wavelength patch antenna elements are positioned on the array face and each positioned adjacent a respective subarray assembly. The millimeter wavelength patch antenna elements each include a driven antenna element having a front and rear side and a parasitic antenna element positioned forward of the front side of the driven antenna element. A microstrip quadrature-to-circular polarization circuit is positioned rearward of the rear side of the driven antenna element and operatively connected to the driven antenna element. A single millimeter wavelength feed operatively connects the microstrip quadrature-to-circular polarization circuit with a respective adjacent beam forming network module supported on the orthogonal positioned subarray assembly.
